Python 10个面试题实例
当然！以下是10个Python面试题及其示例解决方案的中题目：
1.反转字符串:
string = "Hello, World!"
reversed_string = string[::-1]
print(reversed_string)
2.检查字符串是否为回文:
def is_palindrome(string):return string == string[::-1]result = is_palindrome("madam")
print(result)
3.找到列表中的最大数:
numbers = [10, 20, 5, 30, 15]
max_number = max(numbers)
print(max_number)
4.计算一个数字的阶乘:
def factorial(n):if n == 0:return 1else:return n * factorial(n-1)result = factorial(5)
print(result)
5.检查一个数字是否为质数:
def is_prime(num):if num < 2:return Falsefor i in range(2, int(num**0.5) + 1):if num % i == 0:return Falsereturn Trueresult = is_prime(17)
print(result)
6.计算斐波那契数列:
def fibonacci(n):a, b = 0, 1for _ in range(n):print(a, end=' ')a, b = b, a + bfibonacci(10)
7.计算字符串中字符的出现次数:
string = "Hello, World!"
char_count = string.count('l')
print(char_count)
8.反转列表:
my_list = [1, 2, 3, 4, 5]
reversed_list = my_list[::-1]
print(reversed_list)
9.检查两个字符串是否为变位词:
from collections import Counterdef is_anagram(str1, str2):return Counter(str1) == Counter(str2)result = is_anagram("listen", "silent")
print(result)
10.从列表中删除重复项:
my_list = [1, 2, 2, 3, 4, 4, 5]
unique_list = list(set(my_list))
print(unique_list)
